Maybe you could do 5-6 hours on your section play through. If you haven't played the first portal, I would say 10-12 hours. With playing the first (3 times!) it still took me a good 8+ hours, and I would guess 8-10 for most. I haven't done the Co-op yet, but just the single player was so epic I would also say GOTY candidate.

Also, in portal 2 do you play as the character from the 1st game or do you play as the robots they showed on the commercial?

Both. Single player is the girl from the first game and Co-Op is the robots. AMAZING game btw. Rental for sure and easily worth $40.00 for those looking to buy and support the developers. Either way, everyone should play it.
